摘要

PROBLEM TO BE SOLVED: To provide a toner that is excellent in image density, fixability and temperature preservability, and that can produce high quality images without causing the filming problem; a method of preparing the toner; and a developer using the toner. SOLUTION: The toner includes at least: a binder resin; a colorant; a release agent; and a dispersing resin configured to disperse the release agent. The dispersing resin includes a polyhydroxycarboxylic acid unit obtained from an optically active monomer. The polyhydroxycarboxylic acid unit has an optical purity X of not greater than 80% in monomer component, wherein the optical purity X is defined by the following equation: X(%)=¾X(L)-X(D)¾, wherein X(L) represents a mole percentage of an L-monomer in the optically active monomer, and X(D) represents a mole percentage of a D-monomer in the optically active monomer.
